GLSA-202211-09 : xterm: Arbitrary Code Execution

critical Nessus Plugin ID 168060

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202211-09 (xterm: Arbitrary Code Execution)

 - xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions. (CVE-2022-45063)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All xterm users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=x11-terms/xterm-375
